So what is the explanation for this aspect of MWI? I am asking for a local causal physical explanation for the observed facts. Nothing else will suffice at this point.

Not so in the MWI. > The influence is non-local, that does not imply FTL. If there is no non-local influence in MWI, how is the observed correlation formed? Just answer the question.

Price and Tipler, indeed, just reproduce the standard non-local quantum account. If you are so convinced that these papers give a fully local explanation for the violation of the Bell inequalities, then reproduce the argument here so that we can agree on what, exactly, we are talking about.
